UNITED STATES PATENT OEEIGE.

FRANK W. GROFF, OF INDIANAPOLIS, INDIANA.

IMPROVEMENT IN PORTBALE FENCE.

Specification forming part of Letters Patent No. 88,782, dated April 13, 1869.

To all 'whom it may concern:

Be it known that I, FRANK W. GROFF, of Indianapolis, in the county of Marion, and in the State of Indiana, have invented an Improved Portable Fence; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked theron.

The nature of the invention consists in the construction and use of the key and base, hereinafter described; said device to be made of wood or any other suitable materials.

To enable others skilled in the art to make and use my said invention, I proceed to describe it more fully, as follows:

Figure l of the accompanying drawings is a View of two adjacent panels of the said fence C D, the said key; C D of Figs. 4 and 5 views ot the same; K, K', and K" of said Fig. 1 and K of Fig. 3, views of the said base; Fig. 2, a sectional View of the way in which the key C D is let into the inortise F G of the plank A B, which mortises in the plank A B are more fully shown by F Got' Fig. 6 of said drawings. L' and L' of the said Fig. 6 are views ot' the tenon which is to t into the mortise L of the base K of Fig. 3. G' and G' of said Fig. 6 are slots cut in the upright battens opposite the mortises F G and F G, to more nicely accommodate the key C D.

To use my said device, the panels of fence are set up, with the ends of the post resting in the bases K, K', and K". The keys G D and C D are then put into the mortise F G and F G. This will hold the panels firmly in their places.

. When the keys of two adjacent panels are loosened, either panel will, by reason of the shape of the mortise L in the said base, the shape of the tenon L', and the shape of the key C D, be free to turn on its posts as a gate does, and can be swung around against the other panel in the direction ofthe arrow O P, or the reverse, and by this means any panel of the fence may at an instants notice be converted into a gate. The panel can be just as easily swung back and keyed up as before, so as to make the fencecontinuons.

What I claim, and desire tov secure by Letters Patent, is-

1. The combination of the key C D and the rnortise F G, when constructed and used substantially as herein set forth.

2. rlhe base K, when constructed with the mortise L and combined with the tenon L', and otherwise made and used, substantially as herein set forth.

In testimony that I -clailn the foregoing specification I have hereunto set my hand this Y 7th day ot' January, 1869.

FRANK W. GROFF.
